• Performing a fuzzy search may retrieve terms with similar spellings: so sanh y nang x hoi. ((hieu van) OR (hieu va)) cam xuc van hanh vi ((cu tren) or (tu tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sanh y nang x hoi. ((hieu van) OR (hieu va)) cam xuc van hanh vi ((cu tren) OR (tu tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sanh y nang x hoi. ((hieu van) OR (hieu va)) cam xuc van hanh vi ((cu tren) or (tu tren))".
• Adding a wildcard symbol may retrieve word variants: so sanh y nang x hoi. ((hieu van) OR (hieu va)) cam xuc van hanh vi ((cu tren) or (tu tren))*.
